Birds of a feather may flock together, but don’t expect them to have the same musical tastes.
Case in point: One of YouTube user Mark Muldoon’s cockatoos loves headbanging to an Elvis song played on acoustic guitar, while the other cockatoo would rather be anywhere else. The disparity in their energy levels, as seen in this GIF, is smirk-worthy.
Different strokes for different folks, we suppose.
While the happy cockatoo evinces minor enthusiasm throughout the video, things really pick up around the 1:40 mark.
